p i Specification of Letters-Patent Patented blur. 14 1911;- Application med A ril 12, io o. Serial No. 555,901.

To all whom it may. concern:

Be it known that I, Oscar: Rrrz, a citizen of the United States, residing at Newark, in the county of Essex and State of New 'Jer' soy, have invented certain newand useful Improvements in Resilient Bearin s; and I do hereby declare the following to be a full,

clear, and exact description of the invention, such as'will enable .others skilled in the art, to which it appertains to make and use the same, reference being had to the accompanying drawings, and to characters of reference. marked them-ion, which form a part of this specification.

This invention has reference, generally, to

improvements in resilient bearings; and, the

invention relates, more particularly, to illiprovc'i'nents in that class of bearings used with shafts or spi11dles',rotating at high speeds, as in centrifugal machines, creamseparators, turbines, and machines, motors and engines of any general construction,

running at high speeds.

The invention has reference, more espe cially, to improvements in the neck-bearings of cream-separators .with a view of provid ing' a novel resilient bearing,so that the shaft or spindle oi the machine may freely and automatically assume its natural gyratory axis.

'lhe invention has for its further object to provide a novel, simple and ctl'ectivcly operating resilient bearing for the shafts or spindles oi the various kinds of machines, motors and engines herein-above stated, and to provide more especially a novel form of resilient neck-bearing for creaiii-separators, and to provide a bearing,,the parts of which. can be readily regulated andadjusted, and that the amount of the resilience can be regulated so that the fast-running shaft will run true and will not be subject. to any objectionable oscillations.

Other objects of this invention not at this time more particularly enumerated will be clearly understood from the following de-' tailed description of the present invention.

With the various objects of the present invention in view, the said invention consists, generally, in the novel resilient bearing hereinafter set forth; and,'-thc. invention consists, furthermore, the novel'arrangements and combinations of the various de vices and parts, as well as in the details of the construction of. the same, 'all otwhielr rn1ore,,gtix 1 ly described in the followingspecification, and then finally embodied in the clauses of the claim wh ch are uppended to and which form an essential part of the said specification.

Theinvention is clearly illustrated in the accompanying drawings, inwhich:

Figure 1 is =1 view partly in side elevation and partly in vertical section of the frame and bowl of one form or style of cream separator, showing the neck-bearing in vertical section; and, in side elevation, insaid neck-bearing, a resilient bearing made according to and embodyin the principles of the present invention. hi. 2 is a top. or plan view of the resilient bearing, said view being made on an enlarged scale; Fig. 3 is a horizontal sectional representation of the' same, said view being made ona larger" scale; and Fig. 4; is a transverse vertical section of said resilient bearing, this view' being made on a still larger scale. Fig. 5. is. a view of a portion of a'creani-separator, the frame and the neck-bearing thereof being represented in vertical section, and the bowl being shown partly in elevation and partly in vertical section, said view showing in connection therewith, and in vertical section, a resilient bearing of a slightly modified form, but still-embodying the principles of this' invention; and Figf (5 is a hor zontal section of the said resilient bearing, the said view being made on an enlarged scale. Fig. 7 is a horizontal representation of a resilient bearing of another modifiedconstruc- 00 tion, but still embodying the principal features of the present invention.

' Similar-characters of reference are employed in all of the above described views,

to indicate corresponding parts. Referring now to the several figures of the drawings, the reference-character l indicates -the usual frame-work of any wellknown style of cream-separator provided with the neck-bearing 2, in which the resiliout bearing made according to the present -invention arranged, substantiallvin the manner illustrated'in Figs. 1 and 5 of the drawings.

"The reference-character 3 indicates the} usual bowl, of which 4 is the cone-shaped bottom formed with the member or element 5 from which extends in a downward direction through the resilient bearing of the present invention, and throu h an opening 11 '6, the, usual. and rapidly revdlving shaft or -spindle 72 The said resilient bearing which 2 i v a 986,862

is more particularly shown in Figs. 2, 3, and 4.013 the drawings consists, essentially, of a cylindrical tubular body 8 which is formed upon its upper portion with aflat disk-like member or element 9, said member or element being provided with an annular marginal flange 10, and an inner marginal flange 11, preferably of a. triangular or similar 'configuration," substantially as illustrated, 1 andthe saidfiange 11 being provided with suitably formed oil-ducts, as 12, leading from the lubricant-containing space 13, formed by said'eleinent 9 and its flanges 10 and 11,

into the tubular bearing-member or body 8,- 5 as will be clearly evident. When the parts are assembled inthe mannen shown in said Figs. 1 and 5, thesaid space 13 contains a suitable packing, as 1-;l,-or other lub'ricantsoaked material. As illustrated, the said tubular bearing-member or body 8 is provided with a number of screw-threaded sockets or holes, as 15, usually four 'of them,

as represented in Fig. .3 of the drawings,

- although but three of such sockets or holes .may be used, as indicated in Fig. 7 of the drawings; but, it will be evident that more than three orfour of such sockets or h'oles 15 may be employed when found necessary,

as in the larger sizes of 'esilient bearings;

.30 Screwed into tliesaid screw-threaded sock-,

ets or holes 15 are. the screw-threaded endportions 17 of suitable pins 16, said pins .thus beingmade to radiate from the said tubular bearing-member or body 8, and each pin being,forni ed in its end with a slot or groove 18 for the arrangement of the end of ajscrew-driver therein for securing each pin in its 'tixed-position.

, The reference-character 19 indicates a suitably formed tubular body or ring shaped element which is provided with a number of suitably disposed holes or openings, as 20,

these holes corresponding to the number of pins 16 which are employed. As shown in the several figures of the drawings, the slot- =ted end-portion of the said pins 16 extend into the said holes or openings, the said holes being a' trifle larger than the diames ters of'the pins, nsually about-one sixtyfonrth of an inch, more or less, and the ends of the screws not extendin beyond the outer cylindrical surface of the tubular bearing-member or body 8, but terminating 'preferabl y about one sixty-fourth of an inch backof the outer surface of said member or body 8, so that the rim is not fixed with relation to said body and its pins 16.

EIXCII'ClIDg each pin 16 is a coiled spring 21 ot the-proper tension, and loosely 'arranged upon each pin is a bushing or nut justed relation by means of the set-screws 27. The previously mentioned springs 21 are arranged between the nut-shaped ends of the said nuts or elements 24 and the inner cylindrical face-portions of the said parts, andfor the purpose of regulating the tensions of said springs.

bearing of the cream-separating machine is hown in Figs. 1 to 4 inclusive. the forms of bearings illustrated iii-Figs. 5, 6 and 7 may be 'used, inwhich' case the nut-like .inei'nbers or bushing 22 and the adjusting description of Figs. 1 to l inclusive, and the remaining parts of the resilient bearing are Figs. 1:, 2, Band 4. i From an inspection more particularly of Figs. 3, 4, 6 and 7 of the drawings, it will shaped element 9 with relation to the tubular bearing-member or body 8is capable'of a multiplicity of vibratory movements in horizontal planes at right angles to thelversame time, however, the said body or ringshaped element 5) is also capable of'a multl plicity of oscillatory or rolling-movements said horizontal planes, limited; of course, to the space found between the marginal cylindrical suriace-portion of the free'end of said pin extending into the said holes.

From the foregoing description of my I haue devised a simply constructed and efficient hearing which may be used with rapidly revolving spindles or shatts'of inachines of anv style and class, and .which .is
